BUFFERS

Electrolytes A substance that conducts electricity in solution form is called electrolyte. Its example is sodium chloride (NaCI). Many fluids contain strong electrolytes hat break down (ionize) into ions. Most acids and bases are electrolytes. cid n acid is a substance that releases hydrogen

The substance which resists change in pH is called buffer. Stable internal environment is maintained in animals. It requires a relatively constant pH of the body fluids. A strong acid or base can destroy cell stability. Similarly, opposite charges attract each other and form
